Any ideas for student interventions? Any resources for a psychology researcher?

I'm a researcher in the Stanford psychology department, and I'm new to the community. I'm in the process of creating online interventions for middle school students, and I'd like to get a few ideas.
In the past, researchers have used self-affirmation to buffer against the negative consequences of stereotypes. They've also taught students Carol Dweck's growth mindset or strategies for being more engaged in their studies. Any ideas for future interventions?
I've also spent several hours navigating the site in search of resources that could benefit a group of psychology researchers. Let me know of any places I should look.
Thanks!
